Description
Technical field
The present invention relates to a kind of for determining the method for the blocking end in road traffic and the device related with this.
Background technology
Road traffic blocking is the worry globally occurred, and what is be associated is significant economic loss.
Therefore, for a long time exist block report with block warning device in this related mechanism.For example there is blockings
Alert panel and the blocking caution board of electronics on a highway or the blocking warning notice in radio or for leading
The warning message of boat system, the blocking alert panel alerts possible blocking on the entrance to highway, described to block police
Board is accused to attempt to prevent or mitigate to block by suitable rate limitation and Pointing sign board.
Relatively new behave is, movable information is automatically sent to assessment clothes by the application in smart mobile phone
Business.
The service needs the relatively high accumulator property of smart mobile phone, because necessary periodic transmission movable information is to stifled
Service provider is filled in, so as to realize relevant report, that is, whether occur blocking and which section it is currently located at.It is right
This is it must be taken into account that the user of increased quantity adjusts it for passing based on the doubt on data protection law for the sake of with caution
The wish of defeated corresponding data.Perhaps, such identification reliability of service that blocks will suffer from losing in this regard.
Therefore it is desirable that, a kind of possibility is provided, can be realized in a reliable fashion, identification blocks and its side
Boundary protects the accumulator of mobile radio apparatus and additionally protects the privacy of mobile radio apparatus user herein.
Invention content
It is an object of the present invention to propose a kind of possibility, the shortcomings that avoiding or at least reduce in the prior art known
At least part.
According to the present invention, the task is by the method according to independent claims and by according to claim arranged side by side
Device solve.
Here, the technical solution of independent claims is related to a kind of side for the blocking end being used to determine in road traffic

Overlay area in signal quality modeling.
Signal quality Figure 11 can be obtained as being described below：
Y=f (x), wherein y correspond to channel income (also referred to as gain) or received signal intensity (such as with dB) and
Wherein x corresponds to the position in the overlay area of base station 110, here, x can be construed to the scalar to be compared, the scalar
The direction of motion can be shown by the comparison with another such scalar.Herein it is assumed that in the overlay area of base station 110
It is applicable on edge：0=f (0).
Another task of signal analysis device 113 is to determine determining signal quality information 21 in signal quality map
Distribution on 11.Here, determining for the quality information 21 of signal can be carried out in real time.Whereby it is possible that determining in base station
Blocking beginning and/or blocking end in 110 overlay area.
For this purpose, a kind of example of algorithm is described below：
For example, assuming that, traffic jam starts at the edge of the overlay area of base station 110 and in the covering of base station 110 first
Somewhere terminate in region.
Here, the determining signal quality information 21 of mobile radio communication apparatus 200 corresponds to the base station in moment t
Motor vehicle in 110 overlay area, wherein：
Y (t)=[y1 (t), y2 (t) ...], the wherein footmark of y correspond to vehicle ID.
Thus a series of vectors are obtained, the vector has the information of the motor vehicle in the overlay area in base station 110.
It is consequently possible to calculate the probability density function pyt (y) of whole measurements in time interval [t0, t1].
The probability density function of function f (x) is calculated as pf (y).
Calculate the high frequency section of probability density function：
Ph (y)=pyt (y)-k*pf (y), wherein k are equal to the factor of the low frequency part of pyt (y) and pf (y).
Possibility for a kind of practicality of calculating is：
The filtering can be carried out, for removing such measured value for corresponding to the motor vehicle in being not at blocking.
Here, the filtering may also individually be related to the motor vehicle in blocking.However, therefore only retain the machine in blocking
Motor-car.
Thus obtain the model for ph (y), for can be determined respectively in the position for being applicable in f (x)=y0 block boundary,
That is, block beginning/blocking end.The following point of this representative function ph (y), dashes forward in the slope of the function curve of the point ph (y)
So increase, therefore corresponding at least 75 °.It is particularly preferred that the slope corresponds between 80 to 90 °.
The invention idea can be summarized as follows.A kind of method, a kind of system and a kind of device related with this are provided, by
This can become it is possible that determining blocking region along traffic route.For this purpose, using from vehicle-mounted mobile radio communication apparatus
It is emitted to the data on the base station being connect with mobile radio communication apparatus with complying with standard to determine the vehicle in blocking.
Then, the end of blocking is can be inferred that by resulting probability density function.It is possible thereby to using the stifled of blocking is defined
The plug beginning determines blocking region and is therefore especially to determine to block the beginning with end is blocked.These data can be transferred to phase
The motor vehicle answered and/or warning system is blocked, can especially to alert the motor vehicle in being also not at blocking and at once
And dynamically avoidance route is provided for it.
If determining to block along the traffic route in the region of base station, however do not determine to block boundary, then therefore
It can conclude therefrom that, be completely in blocking along the traffic of the traffic route in the masked areas of base station.Then, may be used
Boundary is blocked to seek in other base stations or determine.Thus, it is possible to it across base station determines along the blocking of traffic route being related to
Region.
